Dear Group, I run a lengthy batch program I created with VBA. AutoCAD stops with a "not enough memory, Abort Retry Ignore" message at the same spot each time, 1.8 gigs of ram used (according to Task Manager). I have maximized my paging file size. I have 2 gigs physical ram and a dual 2.6 gig processor. Autodesk, please what else can I do? The mem used by AutoCAD keeps increasing as the program runs and I need to be able to release it for the program to continue. I've tried using VB as a controller but things only get worse. Any repeated process will eventually make AutoCAD lock up. Please help! Thanks, Rick
